Desert road between Ahwaz and Kermanshah

It was a full day's drive between Ahwaz and Kermanshah, and we had to cross the desert to the north of Ahwaz.
Ahwaz is one of the hottest cities in the world with the summer temperature often around 45°C (113°F).
In the desert it is even hotter, and that day the heat inside our un-airconditioned Fiat 1500 was unbearable.

We had been well prepared, carrying plenty of extra water,
but even so the thought of a breakdown was always on our minds.
There was little traffic and there were no repair facilities until Kermanshah.
